Abstract

A multi projector imaging system is provided. The system includes a plurality of projectors and a computing device in communication with the plurality of projectors. The computing device includes a projector platform module providing output to the plurality of projectors such that the plurality of projectors display partially overlapping output as a cohesive display. The projector platform module includes a projection player module having media drawers for preparing frames of data that are drawn into a frame buffer for eventual display through the plurality of projectors. The projection platform also includes a remote desktop controller. The remote desktop controller manages remote computing devices communicating with the projector platform, wherein the remote desktop controller specifies a resolution and aspect ratio for image data provided by the remote computing devices, and wherein the provided image data is stored in the frame buffer. A method for displaying content through the multi-projector system is also included.

Claims

3-1. The system of claim 1, wherein the network module includes a dynamic host configuration protocol (DHCP) server for assigning a unique IP address to computing devices in communication with the computing device over a network.

8. A method for displaying content through a multi-projector system, comprising:

establishing a remote desktop connection with a computing device and the multi-projector system;

requesting an image resolution and aspect ratio for data transmitted from the computing device;

storing the transmitted data in a portion of a frame buffer assigned to a projector of the multi-projector system; and

displaying the transmitted data within a region of an image displayed through the multi-projector system, wherein the image displayed through the multi-projector system is a unified display in which output from multiple projectors partially overlaps.

9. The method of claim 8, wherein storing the transmitted data in a portion of a frame buffer assigned to a projector of the multi-projector system includes,

processing the transmitted data according to a format type.

10. The method of claim 8, wherein the transmitted data is displayed at the image resolution and aspect ratio.

11. The method of claim 8, further comprising:

scaling the transmitted data prior to displaying.

12. The method of claim 8, wherein multiple remote desktop connections are established and wherein corresponding desktop images for the multiple connections are displayed in the unified display.

13. The method of claim 12, wherein a computing device associated with one of the multiple remote desktop connections controls another computing device having a different one of the multiple remote desktop connections.

14. The method of claim 8, wherein the displaying includes,

modifying the transmitted data according to a calibration dataset that maps between projector device pixels and a previously captured calibration image displayed by projectors of the multi-projector system.

15. The method of claim 8, wherein each method operation is embodied as program instructions on a computer readable storage medium.
